. 1 cam. (01. 43-141) My invention relates to dusting-powder 7 containers, and refers particularly to dusting-powder containers in the form of cartridges suitable for insertion into and employment with powder guns.

One or the objects of my invention is a dusting-material container or cartridge capable of being readily inserted within and removed from a powder gun.

Another object of my invention is a refillable m or non-refillable dusting-material container for the purposes indicated.

Another object of my invention is a self-contained dusting-material container requiring only a powder gun for its operation.

Another object 01' my invention is a dustingmaterial container which does not require perforation in order that it may be employed in a powder gun.

Another obiectoi my invention isv a dustingmaterial container which does not require meployed'in a powder gun.

material container which is dust-proof during handling and shipment.

Another object of my invention is a dustingmaterial container which can be readily filled by mechanical container fillers. Another object of my invention is a dusting- 0 material container, one form of which iswithout moving valve during operation.

Another object of my invention is a dustin material container the contents of which are not exposed during its insertion into a powder gun.

7 Another object of my invention is a dustingmaterial container the operation of which consists simply-in its insertion into a powder gun and the operation of the latter.

Another object or my invention is adustingv material container capableof operation with powder guns of various mechanical constructions.

Another object of my invention is an inexpensive dusting-material container for the purposes described p I The above mentioned andother desirable objects are obtainable by the use of the dustingmaterial container of my invention as will be evident upon a consideration of my specification and its accompanying drawings.

' The chief objectionable feature incldentto the use of most of the devices suggested for the spraying or dusting materials is that they are retained in containers having no relation to the powder gun, and hence they must be opened and the fine dustlng'material poured into the gun; thus rechanical penetration in order that it may be emsuiting in all of the objectionable features oi dustladen air and the possibility of spilling and los-- ing some of the powder.

In using my device, however, a cap is removed and the entire container, or cartridge inserted 5 into any suitable gun without exposure oi. its

contents. 7

It is to be particularly noted that my cartridge isof the most inexpensive construction, costing but very slightly more than an ordinary carton, 10

and that it can be employed with a gun consisting simply of a cylinder construction with a flapvalve, or other suitable inexpensive valve, and it thus possesses all of the desirable properties of a device of this character at a minimum of cost. 15 The many advantages or my device are evident from the following description. In the accompanying drawings illustrating modified formsof the device of my invention, similar parts are designated by similar numerals.

Figure 8 is a vertical cross-section of one form 35 oi my device incorporated within a piston mem- Figure 9 is a left-end view 01' the device of Fig--, ure 8. V Figure 10 is a section through the line 13-43 of 40 Figure 8.

The particular form of the device shown in Figures 1 and 2 consists of a hollow cylindrical cardboard member 2|, one end of which carries a fixedly attached, or glued, to the annular member 21.

A removable plug, or closure, 23 closes the tube 23 when inserted therein.

The other end of the cylindrical member 23 car-' ries a closure consisting of an annular member 23 'having the outwardly extended flange 2'l fixedly- 23 by means of glue or otherwise.

the opening 4| consists of In the modified form of the tubular member 23 shown in Figure 3, the tubular member has a plurality of openings 3l-3i, and the outer end is straight, the tube 23 being maintained in position by means of a binding ring 33 which is fixedly attached to the closure member 2| and the tubular member 23.

In the modified form of the tubular member 23 shown in Figure 4; the tubular member has its inner end 34 turned inwardly, thus restricting the diameter of the tubular member at this end.

The modification of the closure.of the cylindrical member 23, shown in Figure 6, consists of an annular metallic member having an opening 4i therein. This metallic member consists of an exterior U-shaped element 42, extending inwardly at 43, then outwardly at 44 at right angles and then into the V-shaped member 43. The side of the cylindrical member 23 fits into, the U- shaped element 42 to form a fixed. engagement, the outer face of the U-shaped element 42- being preferably flush with the outer face of the cylindrical member '23. A removable closure for,

an annular metallic member composed of the U-shaped element 43. the side 41 and the. right angularly inclined member 43. The opening 43 of the element 43 is covered with a porous disk 3321s previously described. This particular construction is intended for a refillable cartridge, for which purpose the removable closure is removed, the material is inserted into the cartridge through the opening 4!, and the removable closure inserted, thus forming a tight 4 closure for the device. Y The modified form of my device as illustrated in Figure 7 is shown in order to indicate a ring member 3i fixedly attached to the cylindrical member 23 which acts as a stop to limit the inward movement of the cartridge into a powdergun as explained later.

Acover 32 can be placed over the air entrance end of the device if desired, as shown in Figure 5.

The operation of one form of my cartridge is shown in Figures 8, 9, and 10, but I do not limit myself to the particular i'orm of air-pressure member, powder-gun or piston, shown therein which consists a hollow tubular member 33,

over one end portion of which is a telescopically device of my invention.

movable cylinder 34, the outward end of which carries a closure consisting of an annular metallic member having the U-shaped element 33, the element 33 and the annular disc member 51 having a plurality of openings 33-33 therein. Fixedly attached to the disc 31, by means of the rivet 33, and covering the openings 33-33 is a flapvalve 33 of suitable flexible-material, which will close the openings 33-33 when air pressure is brought to bear upon its inner face, and which will allow of the opening of the openings 33-33 when air pressure is brought to' bear upon the outer face of the disc 31. A stop 3| is fixedly attached to the inner face of the member 33, a ushaped metallic ring 32 encompassing the extremities of the members and 3i. A cylin-' drical grip member 3.3 is fixedly attached to the outer face of the. member 33 and a resilient holding member 34 is fixedly attached to the grip 63.

In operation the closure 23 (Figure 1) is removed and the cartridge inserted within the member 33 until it abuts upon stop 3i, the resillent member 34 maintaining it in this position.

The member 33 is then grasped by one hand and the member 34 is given an inward and outward telescopic movement by means of the other hand. Assuming the device to be in the position shown in Figure 8, the inward movement of the member 34 causes the air in the chamber to close the flap valve, thus forcingthe air through the air-Dervious member 23 into the chamber 35 of the cartridge causing the dusting material 33 to escape through; the tubular member 23 and outward of the device in the form of a spray or mist. The outward movement of the member 54 opens the flap-valve 33, allowing air to enter the chamber 33 for the next operation, and as the member 23 is impervious to the dusting material it will not enter the chamber 33.

When the contents of the cartridge have been expelled, the empty cartridge can be readily removed .anda new one inserted, if desired.

From the foregoing description it is evident that nw invention presents an eiiective dustingmaterial containe without moving parts and having the many desirable and 'valuable attributes mentio'n I do not limit myself to the particular size, shape,- number, arrangement or material parts particularly shown and described as these are given simply as a means for clearly describing the What I claim is:

In a dusting-material cartridge, in combination, a casing; a closure for one end portion of said casing having an opening therein; a tubular member extendinglnteriorally from said opening;

pervious to the material within said cartridge during its employment in a powder gun.
